Thanks for this guys. I had an inspection done with a very good Independent after I got my '02 BS. His one comment from listening to the exhaust was he thought the AOS was on its way out.

I ended up taking the throttle body off and yes...there was oil. Not dripping with oil....but a fair amount of oil.

Then I decided to take the throttle body off of my '08 Cayman....and guess what.....EXACTLY the same level of oil.

On both cars there is no excessive vacuum from the oil cap....so I am not replacing the AOS yet on the '02.

I just wish there was a VERY CLEAR description of what the normal level of oil in the throttle body should be. It's been a frustrating thing for me to research.
